Refactor: Remove internal persistence and add Redis helper

- Removed MySQL-based internal data persistence (DB, Conversation, ConversationDB).
- Made the library stateless by removing all internal storage logic.
- Updated Telegram.php version to 1.0.4.
- Added a Redis helper (enableRedis, getRedis) using predis/predis for optional shared Redis client access in commands.
